Power stations
Lesson details
Learning outcome
I can describe how burning fuels can be used to generate electricity.
Key learning points
- Over half of the electricity in the UK is generated from the Sun, wind and falling water.
- Many power stations in the UK burn natural gas and oil to heat water into steam.
- The moving steam in power stations pushes turbines, which drive electric generators that produce electricity.
- Natural gas and oil are fossil fuels used in power stations; coal is no longer used in UK power stations.
- Natural gas, oil, waste and wood are fuels that produce greenhouse gases and pollutants when burned.
Keywords
Electric generator - works like a motor in reverse, generating electricity when it is pushed round
Fuel - a substance that is burned for heating
Non-renewable resource - a resource that cannot be replenished
Pollutant - a substance that causes damage to air, water or land and is likely to harm living organisms
Greenhouse gases - gases in the atmosphere that keep it warmer than it would be without them
Common misconception
Power stations generate most of the electricity that we use in the UK.
Highlight how over half of UK electricity is now generated using renewable energy resources and that power stations contribute about a third of the electricity. Also highlight the continuing need for power stations due to varying weather and demand.
Teacher tip
Electricity made by an electric generator is 'generated' and that from a solar panel is 'produced'. Referring to the 'making' of electricity should be avoided as that implies it is a substance that can be stored.
Equipment
None required.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
